I have a Tivo Premiere with Lifetime (about 2 years old). When I plug the unit it the green power light lights up, after about 45 seconds or so all the lights flash on the front panel and then the unit goes back to power-up mode again with just the green power light lit up. Another 45 seconds later all the light flash on the front panel and well, same thing over and over.
There is no display on the TV, actually when the Tivo is powered up the TV displays a message that the resolution mode is invalid.
I've swapped out the HD with a known good drive. I've swapped out the power supply. Neither provided any resolution. So, any other ideas on what I should try next? Really hate to lose the lifetime service after only 2 years.
